Towing 2500-3000 lbs, flat bed trailer, Rhino and 4 wheeler to go get a xmas tree with family over windy paved road, right hand turn several times steering locked up, flet like anti locking brakes came on and beeping on dash! Scared the heck out of us. Went into oncoming traffic, would have been really bad if cars were closer. Bone stock truck, no lift, no after market rims or tires, STOCK! Only going about 40 mph and tow capacity is 6500... WTH! Going to Toyota to complain! NOT HAPPY!
